Police later recovered three other stolen vehicles and are attempting to link the recovered keys and property to other reports of stolen items.

"They're still trying to uncover which ones he was involved in," police Cpl. Jerry Neufeld said.

He said police believe the man stole cars, drove them around the city and later dumped them while keeping the keys.

Neufeld couldn't provide a time frame in which the stolen property was amassed.

"There's not been any indication," he said. "It's probably going to be a few weeks to a month."

Police photos of some of the recovered property show more than a dozen keys with battery-operated car locks. Police said it's unlikely the recovered keys could have been used in future car burglaries.

"I'm not saying it can't be done, but the odds are very remote," Neufeld said.

Police stopped and arrested Dunne while searching for a stolen Mazda pickup.

Police began their investigation Thursday after a report of a stolen Mazda on the 2300 block of North Spring Street. Authorities later found the stolen vehicle in the area of Southwest 48th Avenue and Bonham Street. Jimmie Ray Dougherty, 27 of Amarillo, was taken into custody and booked into the Randall County jail on charges of possession of a controlled substance and unauthorized use of a motor vehicle. He is being held on $17,500 bond.

Neufeld said investigators will compile details of the crimes and present them to Randall County prosecutors early next week to decide if additional charges will be filed.
